Description

Technical Field

[0001] The present invention relates to the technical field of crystal processing, and in particular to a device and a method for processing calcium fluoride crystals. Background Art

[0002] With the rapid development of semiconductors and advanced manufacturing technologies, the demand for crystals is growing. Calcium fluoride crystals are particularly widely used in the optical field. Due to their excellent light transmittance and low refractive index, calcium fluoride is often used as a material for optical lenses and windows. In laser technology, calcium fluoride crystals are used as gain media in lasers and as optical components in laser systems. Calcium fluoride's low absorption and high light transmittance make it particularly suitable for use in the ultraviolet spectrum, making it widely used in ultraviolet lenses and spectrometers. However, traditional crystal processing still relies on manual grinding, which involves crystal orientation, thickness slicing, and angle deflection grinding, which relies on experience and is performed using a single-axis press. This results in low processing efficiency, with rough grinding taking nine hours to complete one piece. Physical angle grinding relies on the technician's experience, resulting in a scrap rate exceeding 30%, large deviations in physical angles, and high labor and time costs. Summary of the Invention

[0044] S3: Orient the crystal in 111 direction and deflect the crystal in 111 direction;

[0045] S4: Complete quadrilateral angle processing.

[0046] Among them, the reasonable diameter crystal bar specification selected in S1 is D80*60. In S2, the crystal bar is first cylindrically ground for 101 crystal orientation, with the target specification being D70mm. The 101 crystal orientation accuracy is controlled at 23 degrees and 30 minutes by an X-ray orientation instrument. The thickness is sliced ​​by an internal slicer, and the slice thickness is controlled at 21.01mm. In S3, the crystal bar is first cylindrically ground for 111 crystal orientation, with the target specification being D55mm. The 111 crystal orientation accuracy is controlled at 14 degrees and 7 minutes by an X-ray orientation instrument, and the deflection angle is controlled at 20 degrees and 2 minutes. In S4, the quadrilateral angle processing is carried out, and the angle accuracy of each angle is controlled to be less than or equal to 3 minutes, namely 79 degrees and 2 minutes, 89 degrees and 55 minutes, 119 degrees and 58 minutes, and 61 degrees and 3 minutes, respectively.

[0047] During use, a crystal bar of suitable diameter is selected and the auxiliary equipment on workbench 101 completes online cylindrical grinding of the sample, with a diameter tolerance of ±5 degrees. X-ray instrument 210 performs online crystal orientation testing, with an angle tolerance of ±2 degrees. Plane grinding wheel 103 completes online surface grinding of the sample, with a width control range of ±2 degrees and a surface roughness control of Ra better than 0.32. Processing efficiency can reach 1 piece per hour, with a low scrap rate and excellent angular error control.

[0048] In order to apply the above method, an apparatus for processing calcium fluoride crystals is also provided. The apparatus includes a processing assembly 100, comprising a workbench 101, a fixing member 102 disposed on the workbench 101, a plane grinding wheel 103 disposed opposite to the fixing member 102, and a grinding wheel 104 disposed next to the fixing member 102; a driving assembly 200, disposed on the workbench 101, comprising a base 201, a telescopic cylinder 202 connected to the base 201, a motor 203 disposed on the base 201, a rotating rod 204 connected to the motor 203, a first gear 205 sleeved on the outside of the rotating rod 204, and a first gear 205 sleeved on the outside of the rotating rod 204. The second gear 206 meshed with the wheel 205, the tooth groove 207 meshed with the second gear 206, the first rotating arm 208 rotatably connected to the second gear 206, the first bevel gear 209 rotatably connected to the first rotating arm 208, and the X-ray device 210 arranged on the first bevel gear 209; the control component 300 includes a slider 301 sleeved on the rotating rod 204, a clamping rod 302 connected to the slider 301, a control rod 303 connected to the clamping rod 302, a second rotating arm 304 sleeved in the first rotating arm 208, and a second bevel gear 305 fixedly set on the second rotating arm 304.

[0049] The fixture 102 uses a chuck to hold the bar. A flat grinding wheel 103 and fixture 102 can translate horizontally on the workbench 101. A grinding wheel 104 is rotatably mounted on one side of the fixture 102. A slide 101a is also provided on the workbench 101. The grinding wheel 104 is adjustable, pressing down against the crystal bar during machining to grind the outer diameter of the crystal bar to the desired value.

[0050] refer to Figures 2 to 13 In order to ensure that the X-ray device 210 is not affected during grinding, the base 201 is slidably arranged in the slide groove 101a, the fixed end of the telescopic cylinder 202 is fixedly arranged in the slide groove 101a, and the telescopic end is fixedly connected to the base 201; the motor 203 is fixedly arranged on the base 201 and its output shaft is fixedly connected to the rotating rod 204; a slide bar 204a is provided on the side wall of the rotating rod 204; the first gear 205 is rotatably sleeved on the rotating rod 204, the tooth groove 207 is annular, and the tooth groove 207 is fixedly arranged on the base 201; the first rotating arm 208 is rotatably arranged on the base 201, and the first end of the first rotating arm 208 close to the tooth groove 207 is rotatably connected to the second gear 206, and the other end is rotatably connected to the first bevel gear 209; the X-ray device 210 is fixedly connected to the center of the first bevel gear 209. The slider 301 is slidably connected to the rotating rod 204. A groove 301a is defined on the inner wall of the slider 301, into which the slide bar 204a is embedded. A limit groove 301b is also defined in the center of the slider 301. A clamping rod 302 is rotatably mounted on the base 201. A clamp 302a is provided at the end of the clamping rod 302, which is embedded in the limit groove 301b. A limit rod 302b is also provided on the clamping rod 302. A control rod 303 is rotatably mounted on the base 201. A notch 303a is defined on the control rod 303, into which a limit rod 302b is located. A handle 303b is also provided on the control rod 303. A buckle 302c is slidably connected to the clamping rod 302. A spring 302d is attached to the outer sleeve of the clamping rod 302. One end of the spring 302d is fixedly connected to the buckle 302c, and the other end is fixedly connected to the clamping rod 302. The second rotating arm 304 is rotatably set in the first rotating arm 208, and a second bevel gear 305 is fixedly set on the end of the second rotating arm 304 away from the slider 301. The second bevel gear 305 is engaged with the first bevel gear 209. An interface 304a is fixedly set on the side of the first gear 205 and the second rotating arm 304 close to the slider 301, and the inner wall of the interface 304a can be fitted with the outer wall of the slider 301.

[0051] When the grinding wheel 104 is working, the telescopic cylinder 202 is retracted to move the base 201 in the slide groove 101a, staggered with the grinding part, to ensure that the X-ray instrument 210 is not affected; at the same time, when the X-ray instrument 210 needs to be tested, a method for adjusting the angle of the X-ray instrument 210 is provided. First, the telescopic cylinder 202 pushes the base 201 to the specified position, and the motor 203 is started. The output shaft of the motor 203 drives the rotating rod 204 to rotate. The rotating rod 204 is provided with a slide bar 204a which is connected to the groove 301a in the slider 301, so that the rotating rod 204 can drive the slider 301 to rotate. It should be noted that the front and rear ends of the slider 301 are provided with interfaces 304a. The handle 303b can be turned to adjust which interface 304a the slider 301 is connected to.

[0052] The method for adjusting the connection interface 304a of the slider 301 is as follows: rotating the handle 303b can control the movement of the clamping rod 302. Since a slot 303a is provided on the control block 303, rotating the handle 303b can drive the slot 303a to move, and the slot 303a can move the limit rod 302b, that is, the handle 303b can control the movement of the clamping rod 302. When the handle 303b is moved toward the first gear 205, the clamp 302a pushes the slider 301 to connect with the interface 304a on the first gear 205. When the handle 303b is moved toward the second rotating arm 304, the clamp 302a pushes the slider 301 to connect with the interface 304a on the second rotating arm 304.

[0053] Taking the connection between the slider 301 and the interface 304a on the first gear 205 as an example, it should be noted that when the clamping rod 302 moves toward the first gear 205, the buckle 302c is away from the first rotating arm 208, so the first rotating arm 208 can rotate freely; the slider 301 and the interface 304a can be made of a material with greater friction. When the motor 203 drives the slider 301 to rotate, the slider 301 drives the first gear 205 to rotate through the interface 304a, the first gear 205 engages with the second gear 206, and the second gear 206 engages with the tooth groove 207, which is fixed on the base 201, so through Gear transmission, the first gear 205 rotates, which can make the second gear 206 continuously perform circular motion around the annular tooth groove 207, and the second gear 206 is rotatably connected to the first rotating arm 208. The second gear 206 can drive the first rotating arm 208 to rotate with the center of the first gear 205 as the center of the circle. When the first rotating arm 208 rotates, due to the self-locking between the first bevel gear 209 and the second bevel gear 305, the second bevel gear 305 and the second rotating arm 304 can be driven to rotate synchronously, and the X-ray device 210 fixed on the first bevel gear 209 will also rotate, thereby performing rotation adjustment in one direction.

[0054] When the slider 301 is connected to the interface 304a on the second rotating arm 304, the motor 203 drives the slider 301 to rotate, and the slider 301 directly drives the second rotating arm 304 to rotate through the interface 304a, and the second rotating arm 304 drives the second bevel gear 305 to rotate synchronously. It should be noted that the clamping rod 302 is close to the second rotating arm 304 at this time, and the buckle 302c is against the first rotating arm 208. Relying on the restoring force of the spring 302d, it is against the first rotating arm 208 to ensure that the first rotating arm 208 is not affected by the friction of the second rotating arm 304 and rotates. The buckle 302c provides the effect of a brake pad; at this time, the second rotating arm 304 rotates, while the first rotating arm 208 does not rotate. The second bevel gear 305 can now drive the first bevel gear 209 to rotate, that is, the X-ray device 210 on the first bevel gear 209 rotates synchronously with the first bevel gear 209, adjusting the angle of the X-ray device 210 in the other direction.

[0055] Through the above two adjustment methods, the rotation of the X-ray instrument 210 in two directions is controlled by a motor 203, so that the standard crystal orientation angle can be accurately detected during detection, and will not be affected by the grinding wheel 104 during grinding.
